The following is an edited version of the entry in the fourth volume of the Universal British Directory.
Wednesbury is a market town, eight miles from Birmingham, six from Wolverhampton, three from Walsall and five from Dudley. The church is a very fine old Gothic structure. This place is rendered famous for its coal, the best in the kingdom for smiths work, on account of its extreme heat. It runs from three to fourteen yards in thickness, which makes it very valuable to its respective owners, who clear from one to three hundred pounds a week from the sale of that article only. This place also produces that sort of iron ore called blond-metal, used to make nails and horse shoes, and all sorts of heavy tools, as hammers, axes, &c. There are several vessels of diverse sorts made here, which are painted with a reddish sort of earth dug hereabouts, which they call slip. One of the collateral branches of the Birmingham Canal enters this parish about half a mile, to some coal mines not yet opened, and to the iron-works of Messrs. Samuel and John Hallen, iron masters. About two miles from hence are the very extensive iron-works of John Wilkinson, Esq. at Bradley Moor. Its principal manufactories are, guns, coach-springs, coach-harness, iron axel-trees, saws, trowels, edge-tools, bridle-bits, stirrups, nails, hinges, wood-screws, and cast iron goods. Enamel paintings are also done here in the highest perfection and beauty.
Here are three meeting houses, namely, Presbyterians, Quakers and Methodists.
The mail from Ireland, Shrewsbury, and a great part of Wales, passes and repasses through this place every day: the post office is open at all hours.
